Event Bubbling

If a component's event handler method returns true, the handling of that event is aborted. Otherwise, the event "bubbles up".

"Bubbling up" means that if there are no more matching event handlers in the component (see the Multiple Method Matches example)
then the component will trigger the same event in its containing component. The containing component in this example is the page.

Here we have 4 instances of MyComponent. MyComponent renders an EventLink with the event name we give. We give 4 event names: EventA, EventB, EventC, and EventD.
